ER309LSI MIG Weld Wire
ER309/LSI MIG Wire
Class: ER309/LSI AWS A5.9
Conforms to Certification: Weld Process:
AWS A5.9 , ASME SFA A5.9 Used for MIG (GMAW) and Submerged Arc (SAW)
ER309LSI is suitable for joining stainless steels of the 304 type and 347 types. The higher silicon gives arc stability and exceptionally smooth bead appearance.
Tensile Strength 60,500 psi
Yield Strength 89,000 psi
Reduction Of Area 60%
(Material Test Reports Available.)
Deposited All Weld Metal Properties:
Data is typical for ER309LSI weld metal deposited by Mig using Argon + 2% oxygen as the shielding gas. Data on sub-arc is not presented, as sub-arc is dependent on the type of flux used. Other shielding Gases may be used for Mig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration
Both Agglomerated and fused fluxes can be used for submerged arc welding.
Note: The chemical composition of the flux mainly affects the chemistry of the weld metal and consequently its corrosion resistance and Mechanical properties.
